The B-29 "Dave's Dream" returns to airfield in Marshall Islands, after dropping atomic bomb on Bikini Atoll, in Test Able of Operation Crossroads, on July 1st, 1946, during U.S. nuclear testing. The B-29 lands and taxis to a parking place on the ramp. The area around the aircraft is cordoned off and the crew is confined therein as they deplane. Navy photographers take photos. An interviewer talks to crew members. The crew walks away from the aircraft along a cordoned pathway between numerous military personnel on hand to greet them on this historic occasion. The aircraft, number 44-27354, was actually participating in its second atomic mission. It also served as a photographic platform for the mission to Nagasaki on August 9, 1945, when it was named "Big Stink.". Pilot for the Bikini mission was Major Woodrow Swancutt of Wisconsin Rapids, WI. The aircraft was renamed "Dave's Dream" in honor of Captain David Semple, a bombardier killed during the crash of another B-29 on March 7, 1946, near Albuquerque, New Mexico.

Scenes of various atomic bomb tests conducted by America during a course of time. Shows the atomic bomb test in Alamogordo, New Mexico(1945). Nuclear weapons tests for shot Able and shot Baker, tested at Bikini Atoll in the Marshall Islands as part of Operation Crossroads(1946). Close -up view of massive nuclear explosion at sea seen from shore with blast wave approaching unmanned ships near harbor and a palm tree on shore seen waving dramatically. Atomic bomb tests at the Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok) In the Marshall Island as part of Operation Sandstone (1948).

U.S. Nuclear weapons test ABLE in Bikini Atoll also called Bikini Lagoon, on July 1, 1946. Ships anchored in the lagoon in the foreground are seen from aircraft flying above. The nuclear device with yield of 23 thousand tons of TNT equivalent, is dropped from the high flying B-29 bomber named Dave's Dream (not seen) and detonates at a height of 520 feet above sea level. The screen goes white from the light of the resulting fireball. As that light dissipates, the characteristic mushroom cloud is seen billowing upwards, at the same time as a surge of water occurs at the base of the explosion. The upper part of the mushroom begins to separate from the stem, below.

Nuclear weapons test "BAKER" in Bikini Lagoon, on July 25, 1946. Ships anchored in the lagoon are seen from aircraft flying above. The nuclear device with yield of 23 thousand tons of TNT equivalent, is detonated from 90 feet below sea level. The screen goes white from the light of the resulting fireball. As that light dissipates, a huge wall of water is seen rising rapidly to create a mountainous ball of water, from which a mushroom cloud starts billowing upwards. A huge column of water is seen falling out of the mass, as the mushroom cloud continues to rise and spread.

A training film on operations of U.S. forces on Kwajalein Atoll in the Marshall Islands during World War II. A map locates Burlesque and Camouflage Islands. The occupation plan for northern landing forces is to occupy and defend the North Carillon group of islands in three phases. The first phase is 'how hour dog day'. Jasper, Ivan, Albert and Allen Islands are included in the phase. Phase II is 'William hour dog plus one day'. Burlesque, Camouflage and Abraham Islands are included in the phase. Operations of phase III include organization of defenses on Burlesque and Camouflage Islands. Capture of the remaining islands is also included in this phase. The Arlington and the Hollis Islands are to be captured. Officers discuss. Smoke rises from naval guns fire. Aerial view of the target area. A ship convoy bombs the main parts of the atoll. Heavy columns of black smoke rise from the bombing. Air support is provided and naval gun fire is carried out according to schedule in phase I. The island is secure after sometime. Animation depicts occupation of the islands and casualties. Japanese men come aboard a ship as they climb a net.
